CLOSURE AND METHOD OF APPLYING THE SAME.

Application filed July 11, 1923. Serial No. 650,878.

Methods of Applying the Same, of which the i 1 following is a specification, reference being had therein to the accompanying drawin The object of this invention is to provi e a secure closure for a housing in which there is located a part rotating relatively to thehousing, and in many mstances in which a portion of the rotar part extendsthrough the center of the c osure. .This improved closure holds the parts together as a selfcontained handlin unit and serves to keep the grease or ot er lubricant within the housing preventing its escape and guarding the parts housed from the entrance of foreign matter. In the drawings accompanying this application Figure l'shows the mode of applying the closure parts to a housing, the housing and .some of its enclosed parts being shown in section and others in elevation.

Fig. 2 is a view somewhat similar to Figure 1 showing the labyrinth or closure assembled, and

Fig. 3 is an enlarged detail.

As the invention is particularly adapted for use in closing the housin for anti? friction bearings, especially t ose having rolling elements, there is illustrated herein in' connection with the housing, 4, a ball bearing having. outer and innerv rings, 5 and 6, between which there is mounted a row of balls, 7. The irmer ring, 6, isshown mounted upon an adapter sleeve, 8-, of a wellknown construction which is represented as clamped upon the shaft, 9, as for. instance a lineshaft, by means of a nut of some suitable description as for instance the nut 10. The ball bearing is enclosed within the chamber of the housing portion, 11, of a broken away structure, 12 which will be assumed to be a lineshaft hanger box.

It-will be seenfromthe drawings that'the .outer ring has a tight but creeping fit in the housing, the bore ofthe housing being cylindrical for accommodating the cylindrical outer diameter of the ball bearing outer rm y reference to the drawing and particuarly Figure 3, it will be seen that the bore of the housing, 11-, is enlarged at its outer edge as at 13 and 14, and that the face formed by this enlargement has at its center portion a groove, 15, forreceiving the locking ring, 16, presently to be described.

The closure presenting in the illustration an oil groove, consists of two sheet metal plates, 17 and 18. As the selected illustrative example of the invention is a mounting in which the shaft extends through the closure, these platesare shown having a large central perforationfor the accommodation of the shaft or a part carried thereby, as for instance, the clamping nut',.10. The plate,

17, is illustrated in the form of a fiat ring adapted to lie in the inner corner of the recess, 13, and abut against the shoulder, 19, formed by such recess. The closure member,

'18, in cross section is somewhat Z-shaped. The inner part, 20, and that which is shown lying adjacent the extending rotary member is substantially flat, that is,in its initial and unassembledposition it occupies a plane-snbstantiall radial to the housing and the shaft. lutwardly of the portion, 20,there is a portion, 21, bentsubstantially at rightangles, and outwardly of the portion, 21, is a portion, 22, which when the device is assembled closely en ages the-member, 17, and occupies a plane su stantially radially of the shaft and parallel to the plane of the portion, 20. In its initial position, however, it is at an angle to such plane, its outer edge, 23, being slightly oflset from the radial plane. When the entire member, 18, is conber 17 and the portion 22 of the member 18.

Whenit is desired to assemble the closure sidered before assembly, the part 20 is a nut, 10, has a cylindrical outside diameter.

it may be done, either before or after theme which extends outwardly beyond the houshousing and the contained-parts are placed ing, 11, in the-illustrated form- Themed:

'u on :the shaft, as occasion -may demand.

he plate 17 is dropped into position in the recess 13 against the shoulder 19. A s ring ring of square wire which is of s cient 11o dimensions to freely fit within the recess 15 and extend from such recess inwardly of the housing below the base of the recess 13, is provided, and after the member 18 is located'in position, substantially as shown in Figure 1, this spring ring, 16, is placed in the recess 14, and a setting tool, as for instance a spider with-a plurality of feet, 24c, brought to bear upon the portion 22 of the member 18, and this is sprung into surface engagement with the member 17, and sufli- I cient past the recess 15 to permit the spring ring, 16, to snap into position, and the parts assume a position substantially as illustrated in Figure 2, whereupon the closure is securely fastened in the housing and in such a Way that it may be removed when occasion demands by merely prying out the split ring, 16, in a well known manner.

It is to be understood that changes in detail may be made within the scope of the claims without departing from "the spirit of my invention.

I claim as my invention:

1. A body having an open chamber, the walls of the opening being formed with a recess presenting an outwardly facing shoulder, outwardly of such shoulder there being a groove formed in the wall of the recess presenting an inwardly facing shoulder, in combination with a pair of closure plates disposed in such recess, the plates being so formed as to tend to spring apart at their outer edges, and a ring formed of rectan-.

gular wire occupying the groove and engaging the inwardly facing shoulder and overhanging the plates forholding the edges of these together and against the said outwardly facing shoulder.

2 A body having an open chamber, the walls of the opening being formed with a recess presentmg an outwardly facing shoulder, outwardly of such shoulder there being a groove formed in the wall of the recess presenting an inwardly facing shoulder, in combination with a pair of closure plates disposed in such recess, one of the plates being substantially flat and the other being offset, whereby the plates tend to spring apart at their outer edges, and a ring formed of rectangular wire occupying the groove and engaginglthe inwardly facing shoulder and overhanging the plates for weenie holding the edges of these together and against the said outwardly facing shoulder.

3. A body having an open chamber, the walls of the opening being formed with a recess presenting an outwardly facing shoulder, outwardly of such shoulder there being a groove formed in the wall of the recess presenting an inwardly facing shoulder, in combination with a pairof closure plates disposed in such recess, the plates being so formed as to tend to spring apart at their outer edges, and having centrally disposed openings and being spaced apart at and adjacent such opening, and a ring formed of rectangular wire occupying the groove and engaging the inwardly facing shoulder and overhanging the plates'for holding the edges spaced apart at and adjacent such opening,

and a ring formed of rectangular wire occupying the groove and engaging theinward- 1y facing shoulder and overhanging the plates for holding the edges of these together and against the said outwardly facing shoulder.

5. The mode of assembling closures in a recess formed at the'opening of a chamber which consists in squeezing together and against the bottom of the recess a pair of plates normally tending to spring apart at theirouter edges and then dropping a wire ring, rectangular in cross section, upon the plates while held incompression and permittin the ring to expand into a suitably forme groove whereby it in part occupies the groove and in part overhangs the plates for holding the edges of these together.

In testimony whereof, l have afixed my signature hereto.
